T all whom it may concern.-

Be it known that I, JOHN B. HODAPP, of

' Mankato, in the county of Blue Earth and State of Minnesota, have invented a new and Improved Can-Filling Machine, of which the following is a full, clear, and exact description.

The object of my invention is to provide a machine whereby cans employed for the preservation of fruits, vegetables, meats, 8m, may be filled automatically and evenly and the charge pressed down compactly, after which the cans are delivered to a table provided for their reception.

The invention consists of a machine of peculiar and novel construction adapted to carry out the objects named, which machine will be hereinafter fully described, and specifically pointed out in the claims. 7

' Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is aside view of the machineshown in partial section to disclose certain details of construction. Fig. 2 is a front elevation of the machine, also shown in partial section. Fig. 3 is a vertical sectional view taken on line 3 3 of Fig. 2. Fig. 4 is a sectional plan View taken on line 00 a: of Fig. 1. Fig. 5 is a detail View illustrating the construction of the cam employed to operate the feed-slide. Fig. 6 is a plan view of the revolving disk having a cam-,facedridge which operates a lever by which the cans are raised to bear against the under side of the fillers. Fig. 7 is a plan view of the feed-table; and Fig. 8 is a detail View, shown partly in section, illustrating the con struction of the cam employed to intermittingly advance the carrier-belt.

In building such a can-filling machine as is illustrated in the drawings I provide a heavy supporting frame, A A, in which there is mounted a driving-shaft, 13, carrying fast and loose pulleys B B and a pinion, C, motion be-, ing imparted to the shaft by a power-transmitting belt arranged in connection wit-h the pulleys B B. A belt'shifter, G, is arranged so as to shift the belt from B to B, and at the time of such shifting the projecting end of the belt-shifter is brought to bear against the edge of a fly-wheel, 0, thereby checking the momentum of the machine. The pinion C 'engages with a large gear, D, that is fixed upon a shaft, D, mounted above the shaft B in bearings that are held by theframe-work A. This shaft D carries a bevel-gear, D, and a crank, E. The gear D meshes with the gear E, having double the number of teeth, said gear E being carried by a vertical shaft, E, which carries abevel-pinion, a, that engages with a gear, a, mounted on a shaft, F, arranged in the cylindrical chamber F at the bottom of a hopper, F. Upon the shaft F there are arranged four radial blades or arms, b b, which project at right angles from the shaft and divide the cylindrical chamber F into four compartments, each of which compartments is in turn centrally divided by a partition, 0.

Just below the hopper F there is arranged a feed-table, G, which is circular and so mounted that the shaft E passes through its axis, and this shaft E carries arms G G, that are arranged just above the feed-table G, each of which arms is provided upon one side with double semicircular faces 0 0, so that as the arms are revolved through the medium of the shaft E they will scrape up the two piles of matter that have been deposited upon the feed-table by the revolution of the shaft F and its attachments, and will carry such matter forward, so that it will be dropped into the funnel-shaped fillers H, which project from the under side of the feed table, as is clearly shown in the drawings, an equal amount of matter being deposited within each filler.

The openings at the bottoms of the fillers H are closed by a slide, d, the construction of which is probably best shown in Figs. 2 and 4.. This slide is formed with an upwardlyextending plate, at, which is borne upon by a peculiarly-shaped cam, H, which is shown in detail in Fig. 5, said cam being provided with friction-rolls 6, arranged to bear against the face of the plate dI The plate d is rigidly connected to a rod, 6, which is supported in a block, e, fixed to the frame A. A spiral spring, f, one end of which is fixed to the block 6, is coiled about the rod e,and fixed at theothe'r end to a collar, f, that is carried by the rod 6, the tendency of the spring being to throw the slide in the direction of the arrow shown in Fig. 4, so as to bring the openings in the slide at in register with the openings in l the bottoms of the fillers H H, this being to act.

done at the time when either of the recesses forf of the cam H will permit the spring The relation of the gearing D, E, a, and a is such that the shaft F isrevolved a quarterrevolution for every full revolution of the shaft D, while the arms G G are carried through half arevolution for every full revolution of the said shaft D.

The cans to be filled are delivered from two vertical cylinders, J J, within which they are piled, to an endless sectional carrier-belt, I, that is mounted upon and driven by two hexagonal drums, I I, said drums being journaled in the frame-work of the machine, as best shown in Fig. 1. Every other section of this belt I is provided with can-holding pins hit, the pins 71 being arranged upon either side of the cans .while the pins h are arranged to come just behind the cans. I Upon the other sections of the belt there are arranged supporting-stands K, having rearwardly-extending spring-arms k, the purpose of these stands K being to support the column of cans held within the cylinders J when the machine is in the position shown in Fig. 3.

Upon the end of the shaft of the drum 1 there is loosely mounted a lever-arm, L,which is adjustable as to length, and connected by the connecting-rod L to the crank-arm E; and

- as the lever-arm L is slightly longer than the crank-arm IE, it follows that at every revolution of the shaft D a reciprocating motion will be imparted to the lever L, the idea being to bring said lever into engagement with pins Z, that are mounted so as to project through the end plate, Z, as shown in Fig. 8, three of said pins being employed, they being located at every other angle of the drum and held extended by springs Z, but being so arranged that when :the lever L is on its downward stroke they will be pressed inward, the lever at this time sliding over their bevel-faces m.

From this construction it follows that at every revolution of the shaft D the drum 1 will be carried forward one-third of a revolution, which movement of the belt will carry the cans from their position in the bottom of the cylinders J to a position just beneath the fillers, the cans sliding down the spring-arm it into engagement with the pins h h of the following section, being at this time guided and held by rods not, which extend across the upper face of the belt and are secured to the cylinders J and to a receiving-table M, two of these rodsnbeing used in connection with each of the cylinders J.

' In order that the cans may be supported above the rods 11,1 provide the sections which carry the pins h h with strips 0, upon which the cans rest, the rods n being arranged beneath the upper face of said strips. As the cans are advanced beneath the fillers H, they are raised so as to be brought against the bottom of a plate, N, that is carried by the fillers, and above which the slide (Z is operated, suit able apertures being formed in the plate N to against the under side of the plate N.

permit of the passage of the filling material. This raising of the cans, as stated in the last paragraph, is accomplished by means of a rack, O, that is pivotally mounted between the of a cam-faced ridge, q, formed upon a revolv-- -ing disk, R, that is mounted at the lower end of the shaft E, the cum (1 being so formed and the parts so timed that, just as the cans pass under the plate N, they will act to raise the lever .P, and consequently throw the cans up Just at the time that the cans are thrown against the under side of the plate N, two plungers, S S, that are carried by the square shaft S, are forced downward into the fillers, so that the material contained by the fillers is forced downward and outward into the cans, motion being imparted to the shaft S by means ofa connecting-rod, T, which engages with the crankarm E, the idea of squaringthe shaft S being to prevent its turning, so that the plungers which it carries will always register with the fillers.

After the cans have been filled the next movement of the belt I will carry the cans just above the drum I, and a still further movement of the belt will carry the cans forward, so that they will ride along over the rods n, being at this time guided by the horizontal arms 12, the forward movement of the cans being brought about by the pressure exerted by the pins or arms h.

The pinsZ engage with a stop-plate, m, at the completion of the forward throw of the lever L, and prevent any backward movement of the belt I.

A roller, m, is arranged forward of the tubes J, to insure the proper seating of the cans on the belt;

Having thus fully described my invention, what I claimas new, and desire to secure by Letters Patent, is
